STUDY, INVESTIGATION AND DEVELOPMENT OF NON-DESTRUCTIVE RELIABILITY SCREENING OF METALLIZED MYLAR CAPACITORS.
Abstract
The purpose of this program was to study, investigate and develop non-destructive techniques for the reliability screening of metallized mylar capacitors that are potential failures, from a lot of high quality production parts. This was an 18-month effort and comprised of three phases: (1) Investigation and application of certain complex measurements of quality, based on dispersion; (2) A study of clearing and burn-in tests under various temperature and voltage conditions, and their effect on capacitance dissipation factors and insulation resistance; and (3) A proof test in which the optimum conditions selected from the Phase II evaluations were further evaluated and compared to a control group. The predominant failure mode was identified as low insulation resistance. The most effective test was an insulation measurement condition in conjunction with a burn-in. The most efficient test was the standard dissipation factor measurement condition for eliminating potential failures. (Author)
